Imogen Heap, born in December 1977 in London, England, is perhaps best known for her collaboration with Guy Sigsworth in the duo, Frou Frou. Frou Frou released their only album, Details, in 2002. She also had a very popular solo album in 2005, Speak for Yourself In January 2006, Imogen Heap performed, "Goodnight and Go," on The Late Show with David Letterman and The Tonight Show with Jay Leno. "Goodnight and Go" was the second single released from the Speak for Yourself album. Over 120,000 copies of the album were sold in the United States. Imogen toured the United Kingdom (UK) in 2006 with appearances at the Shepherd's Bush Empire and The Roundhouse. Her performance at The Roundhouse was the first public concert to take place there since it was refurbished. Imogen made a deal with a new label, White Rabbit, an affiliated Sony company, for her album, Speak for Yourself, to be re-released internationally in April 2006. She has a new track, "Speeding Cars," which she performed on tour in February and March. The video, also featured on the CD release, was shown on the popular VH1 and MTV channels in the United Kingdom in early April. It was released to other television channels a little later in the year. In August 2006, she performed the third single to be released from the album, "Headlock." It was released in the UK in October 2006 along with a special CD. December 2006 saw Imogen receiving two Grammy nominations: one for Best New Artist and one for Best Song Written for a Motion Picture, Television or Other Visual Media, for the song "Can't Take It In." Imogen decided not to tour in 2007 because she was working on scoring for a Disney documentary. On her MySpace blog in the summer of 2007, Imogen noted that she had dropped out of the Disney project to focus on her upcoming third album, which is expected to be released sometime in 2008 and is not yet titled.
